  • Isotope-labeled pyrylium compound
    Patent number: 9347949
    Abstract: The present invention provides a compound represented by the formula (I): or a salt thereof; and a method of quantitatively analyzing an amino group-containing target substance, including labeling a target substance in samples by using, as a labeling compound, two or more of such compounds having a mutually different mass due to isotope labeling, to confer a mass difference to the target substance between two or more samples, and the like.

  • METHOD FOR MULTIPLE QUANTIFICATION OF AMINO GROUP-CONTAINING NON-PEPTIDIC COMPOUND WITH HIGH EFFICIENCY AND HIGH SENSITIVITY AND KIT THEREFOR
    Publication number: 20120252052
    Abstract: A method of quantifying a target non-peptidic compound having an amino group contained in one or more biological samples, which comprises a step of producing a difference in the mass of the target non-peptidic compound between samples, by using a combination of two or more kinds of stable isotopes of a compound represented by the formula (I): wherein R1, R2 and R3 are the same or different and each is hydrogen, halogen or alkyl, or a salt thereof, as a labeling compound; and a kit and the like usable for such method.

  • Safety apparatus determining whether a detected presence is a work piece or a human
    Patent number: 5428279
    Abstract: A safety apparatus wherein a sensor (10.sub.n through 15.sub.n, 16) for transmitting object (M) detection information as a reduction in the output signal energy, is used as a human detection sensor, while a sensor (21-26) for transmitting object (M) detection information as an increase in the output signal energy is used as a work piece detection sensor, and drive of a mechanical moving portion is permitted only when the logical OR output of both sensors has a logical value of "1" corresponding to the high energy condition, thereby reliably ensuring excellent operator safety in a fail-safe manner.
